i am confused perhabs if we divide the angle 360 into a 24 hour thingy.
so 360 degree= 24 hour

ooh maybe the horizontal length is fixed and just the vertical varies.

if you assume that the sun travels in an arc directly overhead then you can get the angular velocity of the sun as\[\omega=\frac{180^{\circ}}{12 \text{ hours}}=15^{\circ}/\text{h}\]then \[\Delta t=\frac{\Delta\theta}{w}=\frac{55^{\circ}-15^{\circ}}{15^{\circ}/h}=\frac{8}{3}h=160\text{ min}\]

but here the sun is at 15 degrees at 8 am so the time zone are a bit messed up. I guess it is plausible as long as the area is right on the edge of a time zone, but you would expect the sun to rise and set around 6am and 6 pm.
